Hershey, Manhattan Beach, Calif., assignors to Kaiser Aluminum & Chemical Corporation, Oakland, Calif., a corporation of Delaware Filed July 28, 1965, Ser. No. 475,399 13 Claims. (Cl. 22523) This application constitutes a continuation-in-part of our prior patent application Serial No. 346,714, filed February 24, 1964, and entitled Dispenser for Sheet Material Wound on Hollow Core Having Rotatable Cap Means Engaging Interior of Core.

This invention relates to a combination merchandising and dispensing carton device or package and more particularly to a merchandising and dispensing package for enclosing a roll or web of sheet-like material, such as aluminum foil, which is adapted to be selectively dispensed therefrom and then severed into desired sectional lengths.

Accordingly, it is an object of this invention to provide an improved carton device or package of simple construction wherein novel means are employed for selectively dispensing portions of a web of sheet-like material disposed within said package.

This and other objects will become more apparent from a review of the following detailed description when considered in conjunction with the accompanying figures of the drawing, wherein:

FIG. 11 is a cross-sectional view taken generally along line 1111 of FIG. 8.

It is to be understood that throughout the drawings like reference numbers will be used for like parts. With further reference to the drawings, and particularly FIGS. 1 and 2, the improved dispensing device or package 10 of the instant invention generally comprises an outer tube-like body or sleeve 12 preferably of a generally cylindrical configuration with open ends 14 and 16, and spaced longitudinal edges 18 and 20. Edge 20 can be provided with suitable serrations 22 or the like if desired. Sleeve 12 can be made of readily available material such as a cardboard which in turn can be initially in the form of a flat blank that is subsequently formed into a tubelike body with the spaced longitudinal edges 18 and 20 defining a slot 28 after the open ends 14 and 16 of the sleeve have been closed by a pair of preferably identical core insertable caps 24 to be hereinafter further described in detail. The longitudinal slot 28 which extends between the spaced edges 18 and 20 is thus closed at the ends thereof by the caps 24 surrounding the ends 14 and 16 of the tube 12.

The roll or web of sheet-like material such as aluminum foil that is to be dispensed is carried by a hollow core 34 (FIG. 2) disposed inside of the tube 12 of the container 10 in such a manner that the outer leading edge 32 of the foil 30 can extend beyond the slot 28 and over the one longitudinal edge 18 thereof in the fashion shown in FIG. 1. The hollow core 34 is of shorter length than the tube 12, as shown in FIG. 2. The longitudinal ends 36 of the core 34 are frictionally connected or operatively affixed to the caps 24 in a unique fashion such that rotation of either cap 24 can cause a corresponding rotation of the core 34 to thereby unwind the rolled foil 30 so that leading edge 32 thereof can be further extended beyond the slot 28 until the desired sectional length is obtained.

It is to be understood that the outer surface of core 34 will have an appropriate length of foil 30 or other web material wound thereon. The amount of material 30 carried by core 34 will be determined by the size of the packaging device and the amount of available space provided between the outer surface of the core and the inside surface of the tube-like body 12. In any event, the amount of material carried should be such as to avoid binding and crinkling of the material 30 against the inside surface of sleeve 12 during the dispensing of sections of the foil 30 through the slot of the sleeve 12. The length of foil 30 is wrapped around the core 34 in substantially tight folds. During dispensing when the desired sectional length of foil 30 has been projected through slot 28 the foil 30 located adjacent the edges 18 and 20 of the slot 28 is brought into contact with the serrations 22 to thereby sever the dispensed section from the roll of foil 30 and thereby re-establish a new leading edge 32 on the foil 30 still remaining wound about the core 34.

To enable the proper frictional connection of the core ends 36 to the caps 24 and thereby provide for rotation of the connected caps 24 and core 34 relative to the body 12, the caps 24 have a unique structure. As best shown in FIG. 4, each of the caps 24, which can be made from molded or press formed material such as any suitable plastic, is provided with an inwardly extending generally tapered or suitably configured boss 40 that can include a tapered outer annular surface 42 which is adapted to frictionally or operatively engage the inner surface 44 of the core at one of its ends 36. To further facilitate the frictional connection of the somewhat frusto-conical surface 42 of a cap 24 with the core 34, surface 42 can have a series of longitudinally extending splines or ribs generally indicated by lines 44' at the right-hand core end 36 as viewed in FIG. 2.

The outer surface 42 of boss 40 extends divergently outward from its juncture with inner surface 55 and terminates in an inwardly facing annular recess portion 46 of greater radial extent than surface 42 Recess 46 is bounded by boss 40 and an annular portion of the cap comprised of a radially extending wall 48 projecting from boss 40 and a cylindrical outer flange 50 generally disposed in spaced parallel relationship to the outer section of boss 40. The overall radial size or width of the recess should be such that a cap 24 can properly enclose its associated body end 14 or 16 as the case may be and at the same time allow freedom of movement between either of the caps 24 and the tube 12. Thus there will always be a slight gap between the inside surface of flange 50 and the oppositely disposed'surface of the tube end 14 or 16.

An annular shoulder 52 is advantageously provided intermediate the ends of the tapered boss 40. Shoulder 52 is adapted to abuttingly engage the radial end surface 54 of the core when the core 34 and an end cap 24 are assembled. The axial extent of the recess portion 46 beginning at the terminal end of the flange 50 and ending at the inner annular surface of the wall 48 and the location of the annular shoulder 52 on each cap 24 are so correlated so as to allow sufiicient axial clearance space between each end 14 and 16 of the tube 12 and the associated inner annular surface of the wall 48 bounding the recess portion 46. In the absence of such a proper axial clearance space a binding engagement could occur between the various wall portions defining recess 46 of either cap 24 and the associated tube end 14 or 16.

The significance of establishing the proper spacial and clearance relationship between the various surfaces of boss 40 and wall portions of recess 46 is due to the fact that there cannot be any binding engagement of the tube ends with the recessed portion or pocket 46, whereby a jamming of the web carrying core could occur. Furthermore, the depth of the recess portion 46 of a cap 24 is such that when the cap 24 is attached to an end of tube 12, it will insure substantial alignment of the ends of the web 30 carried by the core 34 with the shoulder 52 of the cap and the slot 28 of the packaging device.

The innermost end of surface 42 of the tapered boss 40 advantageously folds back upon itself to form the inner wall 55 which along with wall 58 defines a closed end sleeve 56 inside of the boss 40. The sleeve 56 has a bottom planar wall 58 that can be disposed in substantial planar alignment with the outer peripheral wall 48 aforedescribed. The purpose of this planar wall 58 is to provide an outer circular surface of sufiicient area preferably for-price marking when the dispensing device 10 is used as a merchandising carton. It is also to be observed that the caps 24 could be press formed of a metallic material, such as aluminum, instead of a plastic material as aforementioned.

FIG. shows a slightly modified form of cap 59 wherein the like reference numbers correspond to the like parts of the aforedescribed cap 24 in FIGS. 1-4. The inner end of the tapered boss 40 has been modified to include an inner radially extending apertured planar wall 60 formed integrally with the inner end of the tapered boss 40. The outer end of the tapered boss 40 is formed to include one planar wall 62 parallel to the apertured wall 60 and to extend radially outward to connect with the flange 50 instead of the two planar Walls 48 and 58 of the cap 24 in FIGS. 14.

Another advantageous embodiment of the merchandising and dispensing device or package is shown in FIGS. 6 and 9 and will now be described in detail. This embodiment of the invention contemplates among other things that one end of the tube-like container body 12 can have a modified end cap 70 attached thereto. End cap 70 is rigidly secured such as by a tight friction fit or a suitable adhesive to package body 12 while being only loosely fitted with the end of the core 34 associated therewith. As with the aforedescribed end caps or knobs of FIGS. 1-5, the modified end cap 70 can include an inwardly extending suitably configured boss or core bearing member 72, the outer wall 74 of which extends outwardly to connect with a radially and outwardly extending wall 76 of the cap 70. The inner end of boss 72 folds back upon itself to define an inner closed end sleeve 78 in a similar fashion as the aforedescribed end caps 24 wherein the sleeve 78 has an inner wall 80 which terminates at a closed end 82. The outer wall 74 of the boss can, if desired, advantageously have an outwardly extending shoulder or stop 84 disposed intermediate its length which is adapted to abuttingly engage the radial end surface 54 of the core 34 when it is operatively connected to the boss in the manner shown. It is to be understood, of course, that in assembling cap 70 and core 34, core 34 will be mounted on the boss 72 in such a fashion that the core 34 is free to rotate relative to the end cap 70 and its boss 72.

Affixation of cap 70 to an end 14 of the container body or casing 12 can be facilitated, if desired, by providing cap 70 with a pair of inwardly extending peripheral flanges 86 and 88 that are radially spaced from each other in such a fashion so as to permit the insertion therebetween of the associated end 14 of the container body 12. When the container body end 14 is inserted between the spaced flanges 86 and 88, it is positively engaged by the end cap 70 whereby no relative rotation can occur between the end cap 76 and the associated end 14 of the container body 12. T o assure further positive engagement between body 12 and cap 70 it may be desirable to apply a suitable adhesive in a well-known manner to the spaced flanges 86 and 88 or to selected portions of the container body end insertable therebetween.

The other end 16 of the container body 12 in FIG. 6 can advantageously have an end cap 24 connected thereto in the same fashion as aforedescribed in FIGS.-

l-5. Further, the outer surface 42 0f the boss 40 disposed in surface-to-surface engagement with the inner surface 36 of the core 34 can have a suitable adhesive applied thereto if desired. The portion of the boss in direct contact with the inner surface of the core need not be tapered but can be relatively straight and of such a dimension as to fit tightly and lockingly within the core. If desired, the boss 48 of the cap or core turning member 24 can have a core abutting shoulder 52. Thus, it will now be evident that in connection with the embodiment of FIGS. 6 and 9 the operator can merely grasp the packaging device 10 only by the end cap 70 while rotating the other end cap 24 in a predetermined direction in order to rotate the core and effect a selective dispensing or retraction of the web material 30 through the slot 28.

As shown in 'FIGS. 7 and 10, the package :of FIG. 6 can be slightly modified whereby the end cap 24' is provided with a plurality of suitably spaced core engaging fingers -90 of the type indicated in FIGS. 7 and 10. The

fingers 90 are separated by a series of inwardly'extend ing grooves 92 formed in a longitudinal direction in the overall boss 40' such that the bottom of the grooves 92 preferably terminate adjacent the shoulder 52. When the cap 24' is made from a suitable material the fingers 90 can have a certain amount of resiliency which not only facilitates assembly between the boss 40' and the associated end of the core 34 but also provides for positive frictional surface-to-surface or operative engagement 1 between the inner surface 36 of the associated core end and the outer surface 42 of the fingers 90.

Another modified configuration for an end cap that can be used with the package of FIG. 6 is shown in the end cap 24. of FIGS. 8 and Isl. In this instance, end cap 24" can comprise an inwardly extending boss 94 which is advantageously formed in such a fashion so as to engage or encompass the outer surface of the V associated core end and to be :operatively connected thereto. To this end, the inner portion of the boss 94 can have an inner wall 96 opposed portions of which can, if desired, converge in the direction of the arrow A whereby wall 96 defines a sleeve having a closed outer end 98. 'In other words, the wall 96 constitutes a frustoconical section of a cone, the theoretical apex of which is located outside the packaging device 10 per se. The closed end 98 merges with the wall 48 of the recess 46. The outer wall surface 100 of the wall 96 of boss 94 extends outwardly to intersect the wall 48 so as to advantageously define the recess 46 aforedescribed in connection with the other embodiments of the invention.

The inner surface of wall 96 of the boss 94 cont-acts the outer surface 36' of the core at one end thereof during assembly of core 34 and cap 24" whereby wall 96 is in operative or positive frictional surface-to-surface engagement with the associated end of the core 34. It is to be understood, of course, that the extent of engagement between surface 36 and the opposed surface of wall 96 will be such that the inner end of the boss 94 will not crinkle or seriously a'brade the adjacent side edge of the material such as foil 30 folded around the outer surface of the core at the time the container body e-nd'16 is freely disposed within the recess 46. Thus, the free edge of wall can be rounded off to prevent this. If desired an inwardly extending radial rib 97 can also be integrally formed on the wall surface 96 to abuttingly engage the end 54 of the core and thus limit the extent to which the core can be inserted within and locked to boss 94.

When using any of the embodiments of the instant invention illustrated in the drawings, rotation of a cap 24, 24-, 24" or '59 as the case may be in the proper direction will cause a dispensing or retraction of the material 30 through the slot 28. When the desired sectional length of the foil 30 extends beyond the slot it is readily separated from the remainder of the web by passage across the serrations 22 of body edge 20. In the event that core 30 is rotated to such an extent such that the leading edge 32 of the foil 30 is withdrawn into the outer body 12 beyond the slot 28, the operator has only to rotate the core in either direction until the leading edge of the foil 30 realigns itself with the dispensing slot 28. The slot 28 is preferably of sufiicient width between the edges 18 and 20 to enable the operator to easily grasp the leading edge 32 of the web and redirect the leading edge 32 through slot 28.

We are aware that numerous dispensing containers have been contrived which are suitable for packaging and dispensing highly flexible sheet material such a paper and ribbon. In use, such devices ordinarily require that the free end of the sheet can only be dispensed by grasping and pulling the same from the container. This can result in a problem of wastage of material in that where an excess of material is pulled from the dispensing container no convenient means is provided as is provided by the core turning member of the instant invention for effecting a simple retraction of the excess material back into the container. Moreover, where the wound material to be dispensed is metal foil, dispensing solely by pulling on the foil material can produce objectionable wrinkles in the withdrawn portions of the sheet. -It is an advantage of our construction that selected portions :of the foil can be dispensed by rotation of acore turning member or end cap without having to rely solely on the manual pullingof the foil, thus obviating crinkling and objectionable wrinkles. At the same time we have provided a unique throw-away article or dispensing package which can be fully utilized and handled by the user without resort to special wall mounting equipment and the like.

It is also to be understood that it is with the contemplation of this invention to use certain advantageous features of one embodiment of the invention in conjunction with certain featu-res of other embodiments. For
